This drawing is an example showing that each building in Birkenau had to have effective drainage (evacuation of waste water and rainwater), a precaution made necessary by the proximity of the water table and the great number of prisoners.

This drawing served to establish the names of the roads along which the Hungarian Jews were moving when they were photographed by the SS in May-June 1944 (photos published in “L'Album d'Auschwitz” Seuil. November 1993).
